Abstract: 1,251,789. Transponders. STANDARD TELEPHONES & CABLES Ltd. 10 June, 1970, No. 28097/70. Heading H4L. A transponder is provided with means enabling it to respond to an interrogating signal only if it is the nearest transponder in a plurality thereof to the source of the interrogating signal. The invention is described in relation to a road traffic control system in which each car is equipped with an interrogator and transponder for determining the distance between it and the car in front and with means for maintaining a predetermined distance between the cars. A primary interrogating signal is received by the transponder, Fig. 2, frequency-changed at 20 to give a binary address code identifying the lane in which the car is travelling, and compared at 22 with the address set up manually or automatically when the car enters the lane. If the correct address is recognized a response is initiated in circuit 23 and a modulator 24 generates a short R.F. pulse constituting a preliminary signal which is transmitted via transmitter 25. A portion of this signal is supplied via a directional coupler to a mixer 27 together with the received preliminary signal from other transponders which have received the interrogating signal. If a coincidence between the transmitted and a received preliminary signal is detected a second start circuit 29 remains unenergized. If there is no coincidence, circuit 29 is energized and triggers a modulator 30 so that a coded signal giving the information required by the interrogating vehicle is transmitted. Fig. 3 shows the timing of the various signals. Vehicle X sends out a coded interrogation signal X T  and vehicles A, B, C in the same lane respond with preliminary signals A T , B T , C T  respectively after a delay td. The propagation time from X to A, A to B and B to C is t 1 , t 2  and t 3  respectively. Thus signal A T  will be received by B as it is transmitting B T  and signal B T  will be received by C coincident with the transmission of C T  so that further transmission from B and C is blocked.

Abstract: 1295255 Process control SIEMANS AG 21 Nov 1969 [22 Nov 1968] 57223/69 Heading G4A In a data processing installation including a memory having at least two independent regions, data is fed from a number of external devices for predetermined periods alternately to the two memory regions so that processing can continue uninterrupted on the data in at least one of the memory regions. Constructional features.-In an embodiment a pulse from one of a number of pulse generators is applied to register ANF, the generators in this embodiment being such that coincident pulses from different generators do not occur. A control unit 5 initiates a programme interrupt in the computer 1 and activates an adder 6. The address of the pulse generator is passed via the input ADR to the adder 4 in which the address of the generator is added to a basic address specifying which of the memory regions is to be used. This "sum address" specifies the memory cell corresponding to the pulse generator in the memory region being used and the contents of that cell are passed to the adder 6 incremented by "1", and passed back to the selected memory cell. The cycle is repeated each time data and address signals are applied to the device. In a modification the pulses are counted over a particular time. A counter 3 is set at the start of the counting by a register MR1 and then decremented by timing pulses. Its contents are monitored by a comparator which, when it detects "0", causes the basic address of the second memory region to be passed from the register AR2 to the adder 4. Thus any succeeding pulses are supplied to the second memory region and a signal is passed to the computer 1 indicating that the first region is ready for processing. The device may be used to store data in the sequence in which it is presented or to read out data sequentially from the storage cells. The "sum address" in the latter is formed by incrementing the previous address until the number of operations reaches the total number of cells whereupon the other memory region is brought into use. In a second embodiment, Fig. 2 (not shown), pulses from a large number (n) of independent generators are fed to a magnetic core matrix store consisting of n cores each of which is allocated an address. The matrix store is cyclically read, the cycle being such that only one pulse reaches each core during the cycle, and its contents and address are processed as in the first embodiment above. The contents of the component regions of the memory may be represented on a display screen. Process control.-The Specification states that the method of transferring data between external units and the data processing installation described above may be used to control a process, e.g. the measuring processes employed in nuclear physics. The pulses from the measuring sensors may be converted to digital values to produce the store address. The system may also be used with voltage to frequency converters.

Abstract: 1295294 Adaptive processors TEXAS INSTRUMENTS Inc 30 Sept 1969 [23 Dec 1968] 48006/69 Heading G4R In an adaptive non-linear processor there is provided a number of "linear" units, or a single "linear" unit common to a number of subcircuits, these units generating weighting functions which minimize, in a least mean square sense, the error between the output signal of the processor and the desired output in response to an input signal. During a learning mode successive pairs of traning signals are applied to the processor, each pair comprising an input signal u and the corresponding desired output z of the processor. The signals are quantized and applied to the linear units to develop and store the weighting functions. In the subsequent recognition mode modification of the functions by input signals to be recognized is prevented. Linear unit Fig. 7.-Weighting values 1a(j), 2a(j) are stored on capacitors 74, 78. These values, which may be zero initially, are fed back to multipliers 60, 67 via delays 79, 80 for multiplication respectively with the present value u (j+l) of the input signal to the non-linear processor and with the previous value x (j) of the processor's output. During the learning mode the multiplier outputs are added at 63 and the result subtracted at 65, 66 from the desired output z (j +l) of the processor in response to the input u (j+l). The output of adder 66 is muliplied at 69, 70 with the present input u (j+l) and the previous output x (j), the results being added at 72, 74, to the previous weighting values 1a (j) 2a (j) to provide updated weighting values 1a (j+l), 2a (j+l) to capacitor stores 74, 76. During the recognition mode switches 64a, 69a, 70a are open so that the stored weighting values can not be modified. Non-linear processor.-An input signal u (j +l) from source 10, Fig. 8, and Fig. 5 (not shown), passes to quantizer 11, Fig. 3 (not shown), which delivers an output on one of four leads to enable a corresponding column of gates 90 in a matrix of 16 gates. The output x (j+l) of the processor passes to delay 206 which delivers a signal x (j) to quantizer 14. Quantizer 14 enables the gates 90 in one of the four rows of the matrix. Signals x (j) and u (j+l) therefore select one of the gates. In one embodiment, Fig. 5 (not shown), each gate 90 is associated with a corresponding linear unit 92 shown in Fig. 7 and enables gate 81 to pass the various signals to the unit. The weighting values 1a (j+l), 2a (j+l) from the selected linear unit are then multipled with x (j) and u (j+l) and the results added by multipliers and an adder common to all the linear units to give the processor output x (j+l). In a second embodiment, Fig. 8, a signal linear unit 92 is used, the stores 74, 78 and delays 79, 80, Fig. 7, being replaced by stores 220, 221 and delays 224 at each point in the gate matrix. The output x (j+l) is then formed from the weighting values in the selected stores, x (j) and u (j+l) by the multipliers 60, 67 and adder 63 in the linear unit rather than by the common adder and multiplers in the first embodiment. Specification 1,264,387 is referred to.
